Power nap & Time Machine questions
I started to use Time Machine for the first time yesterday (after picking up a 2TB USB3 external drive).
Coincidentally, I also wiped my MacBook Pro with a Retina display's SSD - Installing and updating OSX as far as possible. Meaning time machine was turned on for a completely fresh and upto date 'blank' OSX.
I turned on Time machine after connecting my external drive and being prompted. I chose to encrypt and off it went.
The actual backup was done within 15minutes or so (I dont know the exact time, I wasnt really checking im afraid). But the drive encryption is still ongoing - I've been to bed and its about 55% done!
Is this normal?
With regards to Power Nap, if the MBP goes to sleep after inactivity, the HDD continues to remain active - I presume Power Nap is doing its thing?
However, If I choose to sleep the MBP (via the Apple Menu) the drive appears to stop - Nothing is going on?
I also noticed this while updating via the App Store!
If I started a large download and went away, I'd come back to find the MBP asleep and the download finished (it would have took longer than the 15minutes the MBP takes to decide to sleep itself).
However If I start a download and sleep the Mac - the download stops.
Does Power Nap only work when the Mac goes to sleep due to inactivity?

RE: Powernap, sleep, ...
Encrypting a disk volume does take a fair amount of time, the first time. After that you should not be too bothered by the encryption.
I believe that when you manually "sleep" your rMBP, it will pause the App Store download. But when you just "go away", the App Store download will finish, even if it takes longer than the 15 minute timer for sleep mode, before the rMBP is automatically put in sleep mode.
Powernap will wake your sleeping rMBP to do some maintenance things, such as TM backups and email downloads.

I love this forum. Being so new to Macs it answers questions that I didn't even know I needed to ask. Unknown unknowns.
iPhone 3GS, 8 Gb.
iPod Touch, Retina, 64 Gb.
iPad, Retina, 64 Gb.
MacBook Pro, Retina, 2.3 GHz i7 Haswell, 16 Gb RAM, 512 Gb Flash, Mavericks.

Haha - Glad to see my ignorance helped you out!
Sucks that PN doesnt appear to work instantaneously when you put your Mac to sleep - But now I just wont put my Mac to sleep.
